Major form improvements:
- Custom SMTP/Sieve credentials (separate username/password per protocol)
- Connection testing on save (IMAP, SMTP, Sieve) with localized errors
- preconfig_only mode to restrict domains to preconfigured entries
- Form POST value preservation on save errors (auth selects, passwords)
- Smart host placeholders (SMTP/Sieve default to IMAP host)
Security and bug:
- Fix password re-encryption bug (was comparing raw vs encrypted values)
- Fix XSS: escape label output in special folders form
- Fix parse_url() return value not checked for false
- Fix decrypt() failures not handled (fallback to empty string)
- Sanitize log output (remove raw POST data from log messages)
- Replace weak == comparisons with strict === (PHP and JS)
SQL changes:
- Consolidate 4 migrations (2026021000-03) into single 2026021000
- Remove now unused notify_sound_url column
- Add smtp_username, smtp_password, sieve_username, sieve_password columns
When switching identities, the managesieve plugin still connected to
the default sieve server. Hook into managesieve_connect to redirect
the sieve connection to the remote account's server.
Adds sieve_host, sieve_port and sieve_auth columns to the database,
a Sieve section to the identity settings form, preconfig support for
sieve_host, and localized labels for all 7 languages.
The preconfig previously used a single 'host' field for both IMAP and
SMTP, making it impossible to configure different servers/schemes/ports
(e.g. IMAPS on 993 + SMTP STARTTLS on 587). Also, ssl:// scheme was
silently lost during parse_url() since only tls:// was recognized.
Add imap_host and smtp_host as separate config keys with full scheme
support (ssl://, tls://). The legacy 'host' key is still supported as
fallback for backward compatibility.
- Use $config instead of deprecated $rcmail_config
- Replace array() with short array syntax []
- Replace # comments with // for consistency
- Fix typo: 'threated' -> 'treated'
Add proper copyright notices to all source files with accurate date
ranges per contributor based on git history. Add contributors to
composer.json authors and README.
